What kind of song would you write if your voice is soft? would it rhyme or would it just be written.

something billie eilish esque, if you don't like her style, the look to some other singers such as park jimin.  as soft voice is great for delivering a very empowering message or an emotional message.  a good song to look at would be dean lewis' be alright, you want t be able to get high notes but not getting higher in volume.  do rhyme but put it in a unique patter like ABABBCCAB

your question isn't complete

c, d, e, f, g, a, b, and c.

sometimes western music will also use solfege. the names of these are do ra me fa sol la si (or ti) and do.

to indicate a note a half step higher or lower then the original note, you would say c # (for a half a step above c) or bb (for half a step below b)
